Jesus speaking to the multitudes and His disciples:
Whatever the Pharisees and scribes tell you to observe, you should observe. But don't do things according to their works.
Why? They out all these expectations and heavy burdens and put them on men's shoulders, but they won't move them with one of their fingers.
They make themselves look good and they do it for themselves. They do it to seek out the best places at feasts and the best seats in the synagogues. They do it for the attention of being called rabbi.
It's all for themselves.
He tells the listeners don't seek to be called rabbi. Their teacher is Jesus
And they are all brethren. Their Father is God in heaven.
Goals: be a servant because that is what makes a person great.
Humble yourselves. The one who exalts himself will be humbled.
Jesus is teaching His people it's not about yourselves in this life. It's not about creating the absolute best position and recognition for yourself. It's about Jesus and following Him and being a servant and humbling yourself towards others and him. Don't copy those that do it for personal glory. Do everything for God. Even observing what the Pharisees say.
